Congrats on the at bat. Give your son an attaboy from SW Fla. Sorry to hear of the pending mutiny. Here's hoping your coach grows a brain and things turn around for you. Is he new to the program? What's the makeup of your team, class-wise? (i.e. senior laden, young, very young, good balance, etc.)
Tell your son to keep his chin up and work hard. Tell him to bear in mind that, in spite of the idiots running the asylum, you never know who's watching and perhaps taking note of effort, attitude and accomplishment.
